JJG Debris flow data

Supplementary lists The supplementary materials include the data sources (in xlsx files) and the related figures, and the codes for the Poisson process simulating the surge sequences. 1 SM1, the 63 events of debris flows analyzed in the text, including the occurring date and surge number for reach event. 2 SM2, the 'Debris flow data.xlsx' file, including several sheets: S2-1, discharge for the 63 events; S2-2, time interval for the 63 events; S2-3, velocity for the 63 events S2-4, sediment delivery for the 63 events Each event is denoted by its occurring date, e.g., No.990810 means the event occurring on 10 August, 1999. 3 SM3, probability distributions for the parameters S3-1, distribution of discharge for each event, illustrating that the curves for all the 63 events collapse upon the same exponential curve; S3-2, distribution of sediment yield S3-3, distribution of flow velocity S3-4, distribution of time interval Fig9-11 in the text are just some examples from these. 4 SM4, the code of the Poisson process model, including numerical simulation code (matlab) that produce the surge sequences. 5 SM5, R language code for calculating the power spectral analysis exponent of a sequence and plotting the PSA curve. 6 SM6, R language code for sequence preprocessing with moving average and DFA-1/2/3 exponent calculation
